Climate Control Dosn't Work

[wheelman487]

The Climate control dosn't allow me to switch from Bi-Level. Does anyone know how to fix this.

What system do you have? C60 with a fan switch,temp and select levers or the C68 with the touch pad and LEDs? Are you saying it's stuck in one mode? On the C60 check the vacuum selector valve on the back of the control head. If its leaking vacuum than that is probally the cause. If you have C68 than what LEDs are flashing?

I have a 1978 Buick Regal Turbo and it is the C60 with switches. I could cut off the climite control system with the switch But as soon as I switch it to any outher function it just blows from the floor and defoger. Thank You for your responce. I'll take a look at the vacuum selector valve. If thats busted do you know where I can get another one at?
